Weekly Update for Week of April 25th

National Grid continues to coordinate with NYC DOT to repair the area of Beach Channel Drive adjacent to its work area. Design is finalized and the Contractor has been hired for this roadway work. The roadway work will begin next Tuesday and we are still on track to finish before Memorial Day. As far as the ongoing remediation work, National Grid’s contractor Posillico has completed installation and development of four of the five well clusters. The esplanade work also continues. Topsoil continues to be brought to the site for the planting beds and the frame of the staircase has been formed. The sub-base for the new sidewalk is also being developed.

CAMP data is reviewed and compared to specific NYSDEC/NYSDOH approved criteria, known as “Action Limits.” As a result of this evaluation process, site conditions are categorized into two categories, “Operational Condition” and “Action Condition.” The “Operational Condition” is applicable when the data is below the “Alert, Response and Action Limits”, and means that normal operations can continue. The “Action Condition” occurs when one or more of the fifteen minute average measurements for Dust (PM10), Total Volatile Organic Compounds (TVOC) or Odor Intensity are greater than the background or upwind measurement by the specified “Action Limits.” Reaching an Action Level requires corrective action or stopping work until the condition is addressed or abates. During the period from Monday, April 18, 2016 through Friday, April 25, 2016, two portable CAMP stations were in-use and measured TVOC and PM10. Fifteen-minute averages for TVOC and PM10 data remained below the Action Limit.
